Governing Law and Regulations
Wyoming Department of Environmental Quality (DEQ) Solid and Hazardous Waste Division
Comparison: State vs. Federal
· Rules. Wyoming incorporates by reference the federal hazardous waste storage rules, including those for on-site storage by generators, and adds a notification requirement for hazardous waste small quantity generators (SQGs).
· Administration and enforcement. The DEQ administers and enforces the hazardous waste storage regulations in Wyoming.
HWRR Chapter 1, Section 262(a)(v)
The federal rules require SQGs to immediately notify the National Response Center (using their 24-hour toll free number 800/424-8802) in the event of a fire, explosion, or other release which could threaten human health outside the facility, or when the generator has knowledge that a spill has reached surface water. In addition, Wyoming requires an SQG’s emergency coordinator to immediately notify DEQ at its 24-hour telephone number: 307-777-7781.
